+# Application Landing Zone Agent
 
-Auto-generated agent: build-phase-2
+A deterministic, dependency-light agent that turns application requirements into a Technical Solution Design (TSD) and an editable draw.io architecture diagram.
+
+## Quick start
+
+```bash
+python -m application_landing_zone_agent.cli \
+  --input examples/application.json \
+  --output-dir build/example
+```
+
+The command writes `tsd.md` and `architecture.drawio` and validates both before returning success. The package also exposes `LandingZoneAgent.generate(requirements)` for embedding.
+
+## Contract
+
+Input is a JSON object with required `application_name` and `business_context`, plus optional `environments`, `components`, `integrations`, `constraints`, `non_functional_requirements`, and `assumptions`. Output is a `GenerationResult` containing Markdown TSD text, draw.io XML, and a validation report. See `docs/agent-specification.md`.
+
+## Development
+
+```bash
+python -m unittest discover -s tests -v
+python -m application_landing_zone_agent.cli --help
+```
+
+The implementation intentionally uses only the Python standard library. Configuration is JSON (`config/default.json`) so the same contract works in CI and local tooling.

+# Application landing zone agent specification
+
+## Purpose
+
+Transform application requirements into a reviewable Technical Solution Design and an editable draw.io architecture diagram. The agent proposes a conservative landing-zone view; it does not provision cloud resources or invent unprovided compliance claims.
+
+## Input contract
+
+JSON object:
+
+- `application_name` (string, required)
+- `business_context` (string, required)
+- `environments` (array of strings, optional)
+- `components` (array of objects with required `name`, optional `type`, `technology`, `description`)
+- `integrations` (array of strings or objects, optional)
+- `constraints`, `non_functional_requirements`, `assumptions` (arrays of strings, optional)
+
+Unknown fields are preserved in the TSD assumptions section only when explicitly listed; malformed known fields fail validation.
+
+## Output contract
+
+`GenerationResult` has `tsd_markdown`, `drawio_xml`, and `validation` (`valid`, `errors`, `warnings`). The CLI writes the configured filenames and a `validation.json` report.
+
+## Workflow
+
+1. Validate and normalize requirements without making network calls.
+2. Build a deterministic logical architecture model, retaining named components and integrations.
+3. Render the TSD with scope, requirements, environment strategy, component inventory, integration/security considerations, operational concerns, assumptions, and decisions needed.
+4. Render native draw.io XML with title, environment/container layers, components, and directional edges. IDs are stable (`component-<index>`, `integration-<index>`).
+5. Validate required TSD headings and XML structure, then write output atomically through the CLI.
+
+## Diagram requirements
+
+The diagram must open in draw.io/diagrams.net as `mxfile`, contain an `mxGraphModel`, use `vertex` cells for components and `edge` cells for relationships, and use escaped XML labels. It must show application components and external integrations, with clear layer/container labels. It may not contain executable code or credentials.
+
+## Validation and errors
+
+Missing required strings, non-object components, blank component names, malformed integration objects, or empty arrays where a list is supplied produce actionable errors. The CLI prints the error and exits 2. Rendering failures exit 1. The library never silently drops a named component.

+# Repository convention discovery (Step 0)
+
+No template or target URL was supplied with the request, so this repository records the conventions used as the implementation baseline rather than claiming an external inspection. The baseline follows a conventional Python agent layout: `src/` package, `tests/` unittest suite, `config/` JSON configuration, `docs/` contract material, and a CLI entry point.
+
+## Required structure
+
+- `src/application_landing_zone_agent/`: importable implementation and CLI.
+- `tests/`: unit and contract tests runnable with `python -m unittest discover -s tests`.
+- `config/default.json`: checked-in, dependency-free configuration.
+- `docs/agent-specification.md`: behavior, contracts, workflow, and validation.
+- `examples/`: human-reviewable input fixture.
+- `pyproject.toml`: package metadata and console script.
+
+## Conventions extracted for this build
+
+- Public behavior is exposed through a small class (`LandingZoneAgent`) and a CLI adapter.
+- Input/output boundaries are typed dataclasses and JSON/Markdown/XML files.
+- Generation is deterministic: stable IDs, ordering, and formatting make output reviewable in source control.
+- Validation happens before files are written and is also available as a public function.
+- Diagram output is native draw.io `mxfile` XML, not an image or proprietary binary.
+- Errors are actionable `ValidationError`/`GenerationError` exceptions; CLI maps them to a non-zero exit code.

+# Validation evidence (Steps 3 and 4)
+
+The committed validation suite covers:
+
+- input contract failures and successful normalization;
+- deterministic TSD generation and required headings;
+- parseable native draw.io XML with vertices and edges;
+- CLI packaging behavior and the three expected output files;
+- checked-in `pyproject.toml`, configuration, example, specification, and source layout.
+
+Run `python -m unittest discover -s tests -v` from the repository root. Run the documented CLI command to perform a human review of `build/example/tsd.md` and open `build/example/architecture.drawio` in diagrams.net. Publication is represented by the commit created for this deliverable; no remote URL was supplied by the requester, so push status is limited to the scaffold commit operation.
